Description
Technical field
The utility model is related to a kind of new double-clutch automatic transmission DCT parking protecting against shock Cam set assemblies, category
In the Technology of Automatic Transmission for vehicle field of auto manufacturing.
Background technology
Sharply increased with fast-developing and amateur driver's quantity of car ownership, automatic gearbox
It is positive that fast-developing trend is presented.Present automatic gearbox mainly has hydraulic mechanical type automatic transmission（AT）, it is stepless
Speed changer（CVT）And double-clutch automatic transmission（DCT）.
In double-clutch automatic transmission, each gear driving gear of speed changer by odd, even several gears respectively with input
Two clutches C1, C2 connection set on axle, clutch C1, C2 alternately transmit power to realize gear switch.
When DCT works, vehicle is first run with some gear, electrical control unit of automatic transmission（TCU）According to related sensor
Signal judge that next gear of work will be entered, because power is not transmitted in gear clutch separation also, therefore instruction hydraulic pressure control
Magnetic valve processed very easily controls gear-shifting actuating mechanism, and this gear is engaged in advance, when vehicle operation reaches shift points, only
The clutch separation that will working is needed, while another clutch is engaged, then automobile is travelled with next gear.
In gearshift procedure, the power of engine is constantly passed to wheel all the time, so the gearshift procedure so completed changes for power
Shelves.Vehicle realizes timing, will greatly improve gear shift comfortableness, while also ensureing that vehicle has good economy
Property, make to make moderate progress in terms of vehicle oil consumption and discharge.
Double-clutch automatic transmission（DCT）EPB Cam set assembly has the work(for ensureing P grades of engagements and separation
With.When engaging for P grades, parking Cam set assembly is by promoting park pawl assembly, in the teeth groove for pushing it into parking gear, realizes
P grades of parked states；When separating for P grades, parking Cam set assembly is rotated in reverse direction, it is ensured that park pawl assembly is from parking gear
Depart from teeth groove, realize and release parking function.Current existing structure exists because parking Cam set assembly is without impact-proof structure
When releasing parking function, the shortcoming of halting mechanism failure.This patent is simple in construction using parking Cam set assembly, easy for installation,
The characteristics of with low cost and reliable operation, and with protecting against shock function.
The content of the invention
The purpose of this utility model is to provide a kind of new double-clutch automatic transmission DCT parking protecting against shock cams
Assembly, the characteristics of its Ju has the mono- ﹑ An dress Fang Bian ﹑ of Jie structures Jian with low cost and reliable operation, and with protecting against shock function.
What the technical solution of the utility model was realized in：A kind of new double-clutch automatic transmission DCT is stayed
Car protecting against shock Cam set assembly, by parking axle, fanning strip, torsion spring, parking cam, parking pivot pin axle, park pawl axle, parking spine
Pawl, park pawl bearing pin, park pawl roller composition, it is characterised in that：Park pawl axle is connected with case of transmission hole axle, is stayed
Car ratchet rear end is connected to park pawl front end by park pawl axle, park pawl roller by park pawl bearing pin axle；Stay
The centre position of axletree, which is fixedly connected on fanning strip, parking axle, is cased with torsion spring and parking cam, parking pivot pin in front of fanning strip
The laterally inserted parking axle front end of axle is spacing to parking cam front end, and the lower end surface of parking cam is contacted with park pawl roller,
Park pawl bearing pin is extend into the stopper slot of parking lower cam end.
Good effect of the present utility model is the spy that its Ju has the mono- ﹑ An dress Fang Bian ﹑ of Jie structures Jian with low cost with reliable operation
Point, and with protecting against shock function.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model exploded view.
Fig. 3 is P grades of binding site figures.
Fig. 4 is P grades of separation point position figures.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings：As shown in Figure 1, 2, a kind of new double clutch
Formula automatic transmission DCT EPB Cam set assemblies, by parking axle 1, fanning strip 2, torsion spring 3, parking cam 4, parking pivot pin
Axle 5, park pawl axle 6, park pawl 7, park pawl bearing pin 8, park pawl roller 9 are constituted, it is characterised in that：Park pawl
Axle 6 is connected with case of transmission hole axle, and the rear end of park pawl 7 passes through parking spine by park pawl axle 6, park pawl roller 9
The axle of pawl pin axle 8 is connected to the front end of park pawl 7；The centre position of parking axle 1 is fixedly connected with fanning strip on fanning strip 2, parking axle 1
2 front is cased with torsion spring 3 and parking cam 4, and the laterally inserted front end of parking axle 1 of parking pivot pin axle 5 is limited the front end of parking cam 4
Position, the lower end surface of parking cam 4 is contacted with park pawl roller 9, and park pawl bearing pin 8 extend into the lower end of parking cam 4
In stopper slot.
As shown in figure 3, when combining for P grades, parking axle 1 is rotated and drives fanning strip 2, and fanning strip 2 is driven by its torsion spring 3
Parking cam 4, now, torsion spring 3 play a part of power transmission.Parking cam 4 promotes park pawl 7 to move downward realization and stayed after rotating
Car function.Meanwhile, parking pivot pin axle 5 is rotated together also with parking axle 1, plays spacing effect.If parking cam 4 can not
Park pawl 7 is depressed and fallen into the teeth groove of parking gear, parking cam 4 will bear against on park pawl roller 9.At this moment, stay
Car cam 4 is not in the position of combination, and torsion spring 3 is deformed, and plays a part of energy storage.After vehicle car slipping, parking cam 4 is rotated and will stayed
In the teeth groove of the press-in parking gear of car ratchet 7, P grades of combinations are realized.
As shown in figure 4, when separating for P grades, parking axle 1 drives the opposite direction of parking pivot pin axle 5 to rotate, and makes 4 turns of parking cam
After dynamic, park pawl 7 is popped up, and P grades of separation functions are realized in parking.Now, the circle of park pawl roller 9 and parking cam 4
Cambered surface is in contact, and park pawl assembly is delivered to parking to the impulsive force of parking Cam set assembly by the arc surface of parking cam 4
On axle 1, it is ultimately applied on housing.
This parking cam 4 with arc structure can bear larger impulsive force, and impulsive force can be delivered into speed change
On device housing, it can prevent that halting mechanism fails caused by impulsive force.Park pawl bearing pin 8 is all the time on parking cam 4
Moved in stopper slot, stopper slot plays vehicle prevents it from causing park pawl 7 to fall into by mistake due to vehicle vibration in the process of moving
In the teeth groove of parking gear.
